CQNVECTOR HEATER CABINET Filed April 11, 1947 2 Sheets-Sheet 2 INVENTOR. F250 M Yu/ve 7 BY 4 Patented Nov. 22, 1949 PATENT OFFICE CONVECTOR HEATER CABINET Fred M. Young, Racine, Wis., assignor to Young Radiator Company, Racine, Wis., a company of Wisconsin Application April 11,

2 Claims.

The present invention relates to what is commonly called convector heaters generally of the floor type and used in residences, offices and the like especially where appearance is an important factor.

Objects of the present invention are to provide a convector heater cabinet of the character having a pleasing appearance and constructed in separate elements with means whereby the cabinet may be knocked down for convenience-in shipping or whereby the elements may be stored in large numbers without occupyingexcessive storage space.

A further object of the present invention is to provide strengthening sheets or strips which are multiply electric welded to the inverse part or inner surface of the corrugations whereby the elements and strips may be very thin and still provide very strong elements and a very strong cabinet when assembled.

An important object of the present invention is to provide vertically corrugated front and side panels, the corrugations having a shape as shown in the figures. In flat panels there generally are numerous protrusions, this is particularly true when the panels are very thin. In addition to the protrusions the panels may buckle, either of which are unsightly especially when viewed at an angle. In the present invention there can be no unsightly protrusions or bulges in the panel from any view point and when reinforcing strips are used as recited in the next above paragraph the panels will be made even stronger than a fiat panel and less apt to be bent or injured.

A still further object of the present invention is to design the elements with which to form a cabinet whereby they may be quickly assembled together by any one of ordinary intelligence by the use of ordinary fastenings, screws or snap buttons, and whereby the assembly of the cabinet consists of but five major parts, namely, the front, two sides, top, back and the damper, which may be assembled to the front panel of the cabinet or packed separately.

To these and other useful ends my invention consists of parts or their equivalents and assembly or method of assembly as hereinafter described and claimed and shown in the accompanying drawings in which:

Fig. 1 is a front elevational view of my completely assembled cabinet less the damper adjusting chain.

Fig. 2 is an end elevational view of the cabinet as shown in Figure 1.

Fig. 3 is a top view of the cabinet.

Fig. 17 is a rear edge view of the panel shown in Figures 15 and 16.

t Fig. 18 is a fractional end view of a modificaion.

I have shown each of the elements with which to form a complete cabinet except the fasteners forsecuring the parts together. It will be noted that each of the elements is thin. When the dampers are attached to the front panel they are closed so as to form a flat assembly.

My Design Patent #124,702, January 14, 1941, has a pleasing appearance, however it will be noted that it must be completely assembled at the factory, the front and end panels being formed in a single piece and therefore this design could not be knocked down.

The front panel of my device is designated by reference numeral Iii, the side panels are designated by reference numerals l I and I2 and the lid is designated by reference numeral l3. Panel 10 is cut away in its top as at 2| for the reception of a grill 22. This grill may be permanently fastened to member I0.

I provide a damper 23 adapted to be hinged at its top as at 24 (see Figure 6). I provide an opening 25 preferably in the bottom center of the grill having at its bottom a key. A ball type chain 26 is secured to the damper as at 21 and extends freely through opening 25 having at its front end secure this panel to the end panels. A number of tongues 32 in the top of panellil are preferably provided for assembly to the coverr'nen'iber l3.

Side panels II and I2 are provided with openings 4040 which are adapted to register with' openings 3| in panel l0. These panels are the. same length as panel l0, as clearly indicated Figure 2.

Clearly panels ll, 12 and I4 and lid 13 may be first secured together, and when thecabinet has been permanently set in place and the heating element fastened to its mounting and connected, the front panel may be secured to the side panels. It will be noted that the top edge of panel I4 is provided with a number ofopenings {ll which register with openings 42 in lid l3. For attaching the four panels together and for securing thelid to the panels I use preferably snap buttons 43. It will be understood that screws of variouskinds may be used for this purpose, certain holes in the panels being threadedor nuts ,may be provided for the screws.

It will be seen that I have provided a cabinet consisting of five major parts which 'are separately manufactured, stored or packedfor' ship ment in either single sets or multiple sets; that the cabinet is attractive in appearance and strong; that each -individual element is; strong and not easily injured when detached.

I have shown the entire convector less the heat exchange core which is generally positioned just above cut away opening 30 in panel Ill. In most installations these cores are supported on their inlet and outlet pipes so that after the cores are connected to the pipes the cabinet may be placed over the core which is not necessarily provided with a fastening to the core although positioning guides may be provided. However, clearly the core may be secured to and supported by the cabinet, this optional arrangement being possible because of the fact that panel In may be attached after everything else has been done to make the installation complete.

It will be noted that the front panel may be secured to the side panels after the heat exchange core has been installed or the front panel may be removed for inspecting the core or damper.

In order to strengthen the corrugated panels, especially panel J0, I provide a strip 44, see Figures 4 and 6. This strip may be spot welded to the inverse side of certain corrugations. It may be as shown in Figures 4 and 6 or positioned on the bottom of panel [0 directly above openin 30; or it may extend from 30 to the bottom edge of opening 2|. Panels H and I2 may also be fitted with such strips and the strips may be the full width of the panel. Clearly when strip 44 is used the panels and strips may be quite thin so the assembly is lighter than the panel without the strip, thus to reduce the cost.

I In Figure 18 I disclose an end view of a modification wherein the grill is in the lid similar to that shown in Figure 7 of my copending application Serial Number 728,105, February 12, 1947,

Having thus shown and described my invention, I claim:

1. A rectangular in horizontal section cabinet for a convector heater of the character described comprising in combination, the front and side panels each being corrugated vertically with the outer perimeter of the corrugations being substantially sharp, forming apexes, the joints between the front and side panels being formed by bringing together the convex sides of half portions of corrugations with fastenings extending therethrough, whereby th joints between these panels are similar in appearance to said panel corrugations the rear panel of the cabinet being flat,itsedgesadapted to lie on the convex side of one half of a corrugation of the side panels with fastenings extending therethrough, to thereby provide a joint with an appearance somewhat similar to said panel corrugations, a flanged lid adapted to fit snugly over the four panels of the cabinet and being secured to the rear'panel thereof, said front panel at its top being cutaway for substantially its length, forming a rectangular air outlet, a grille in said outlet,

5 said front panel at its bottom being cutaway for 'compr-ising in combination, the front and side panels each being corrugated vertically'with the outer perimeter of the-corrugations being substantially sharp, forming apexes, the joints be tween thefront and side panels being formed by at" bringing together the convex sides of'half por-= tions of corrugations with fastenings extending therethrough, whereby the joints between these panels are similar iii 'appearance to saidp'anel corrugations the re'ar panel of the cabinet being flat, its edges adapted to lie on the convex side of one half of a corrugation of the side panels with fastenings extending therethrough, to thereby provide a joint with an appearance somewhat similar to said panel corrugations, a flanged lid adapted to fit snugly over the four panels of the cabinet and being secured to the rear panel thereof, said front panel at its top being cutaway for substantially its length, forming a rectangular air outlet, a grille in said outlet, said front panel at its bottom being cutaway for substantially its length forming an air inlet into the cabinet, a damper having its top hinged to the top of the grille, a spring associated with the damper adapted to urge the damper toward its open position, an opening near the bottom of said grille and intermediate its ends having a keyway in its bottom, a ball chain havin its inner end secured to said damper adjacent the bottom thereof and extending freely through said opening, the space between the balls of said chains adapted to lie in said keyway, whereby the damper may be manually adjusted and locked into position.
